Sometime between 2017-11-30T00:01:08-0800 and 2017-12-01T08:11:54Z, the index.html page at doxygen.lsst.codes/stack/doxygen/x_masterDoxyDoc became the pipe_base mainpage instead of the lsstDoxygen mainpage. No changes were made to either of those packages at that time, and a manual execution of makeDocs lsst_apps produces the correct index.html file. I note that the logs for the release/run-rebuild pipeline before that date (e.g. run 435) show the push to AWS containing both index.html and pipe_base.html, while those after that date (e.g. run 445) show only the former and not the latter. I'm also not sure where the push to doxygen.lsst.codes/stack/doxygen/xlink_master_[date+time] occurs, but that is showing the same problem.
